Delphi7

 Some program's i made to improve my Delphi skill's

RS232 PIN TESTER

 


   The program display's the status of
   the control line's on the RS232 port.
 
   It's also possible to set and
   reset the DTR and RTS lines.



TLC549 VOLTMETER




Experiment to test how to connect some 
electronics onto the RS232 port.
Wel it was even easier than i thought






HOW TO CONTROL A PCF8574P I2C-BUSS I/O PORT EXPANDER






Toggle pin's on the PCF8574P I2C I/O expander.                    
By pushing the "toggle bit" button you can
invert individual bit's. After changing a bit,
the port will be read.
When pushing the "read status" button, 
the actual port status will be updated.









                                                                                           

Read PCF8574. Device adress is: 01000001                                    



MAX127 USED AS 8 CHANNEL VOLTMETER WITH BARGRAPH




  I2C routine's used to read out an MAX127
  8 channel 12bit's ADC.








                  ADDITIONAL FEATURES:
       -Chart, draw's curve of measured value.
       -Logging, write's measured values to disk.








CONNECTING A NOKIA 3310 LCD TO THE LPT PORT.

       

The program "NOKIA3310LCD" is specialy made 
to test an LCD.
It's also possible to send a bitmap picture (84x48 pixels)
to the display.

The program "PIXELSCAN" only convert's pixel data
into ASCII-files, which can be used as data in a 8051 listing.

                                                                                                    routine's.
